What model train scale is 1/100?

The Elusive 1:100 Scale Model Train: A Close but No Cigar

The world of model trains is a vast and varied landscape, populated by countless scales and gauges. While many common scales like HO (1:87) and N (1:148) are widely available and supported, occasionally a modeller seeks a less common ratio. This often leads to the question: what model train scale is 1:100?

The short answer is: there isn’t a readily available, standardized model train scale at precisely 1:100. While many scales boast approximate ratios, a true 1:100 scale doesn’t enjoy widespread commercial production. This leaves model railroad enthusiasts searching for the closest available alternative.

The closest commercially available scale to 1:100 is TT scale (also known as 3mm scale). TT scale is generally accepted to be around 1:101, offering a near-perfect approximation for those seeking a 1:100 representation. The slight difference is negligible for most applications, and the readily available rolling stock and track make it a far more practical choice than attempting to source parts from a non-standard scale.

For comparison, let’s look at other commonly available scales:

• HO scale (1:87): Significantly larger than 1:100, HO trains are a popular choice due to their relatively large size and detail. The difference in scale is substantial enough that mixing HO and a 1:100 representation would appear noticeably out of scale.

• N scale (1:148): This scale is considerably smaller than 1:100, offering a much more compact layout but sacrificing detail. Again, the discrepancy would be too large for harmonious blending with a theoretical 1:100 model.

Therefore, if you’re aiming for a model train experience approximating a 1:100 scale, TT scale is your best bet. The minor difference in ratio is outweighed by the availability of readily sourced components, ensuring a smoother and more enjoyable modelling experience. While a dedicated 1:100 scale might appeal to purists, the practical realities of sourcing materials and finding compatible parts strongly suggest settling for the incredibly close approximation offered by TT scale.
